Hi,
To answer the quesiton above, please kindly check the following:
1, It seems we are facing the issue decribled in this article:
https://learn.microsoft.com/en-us/troubleshoot/windows-client/deployment/processor-not-supported-together-with-windows-version
2, MS has a supported processor list available:
https://learn.microsoft.com/en-us/windows-hardware/design/minimum/windows-processor-requirements
Company may submit for certification (in the Windows Hardware Compatibility Program) Customer Systems running Windows Server 2012R2 and the identified processors until December 31, 2018; after such date, no new Customer Systems will be certified running Windows Server 2012R2.
It indicates that hardware vendor (such as Dell, Lenovo, HP, etc., not the end user) should connect Microsoft for the certification. According to Dell support, the new processor is not get certified. Thus, the "Unsupported Hardware" is expected behavior.
3, As for the workaround, here's an article (from another hardware vendor Lenovo, also Intel Xeon E3 v6 processors) by applying KB4022726. We may try to see if it works, but not guaranteed.

Note: this is not from MS, just for your reference.
4, For the license transfer, it's probably yes. Since this is not a technical question, it's suggested to contact Microsoft licensing center to double confirm.

Hope the above information helps.
